목차
소개
이 문서에서는 Cisco IOS1000 Series CGR(Connected Grid Router)용 IOS 이미지에 포함된 tm_wanmon.tcl이라는 TCL(Tool Command Language) 스크립트의 문제를 해결하고 확인하는 방법에 대해 설명합니다. 이 스크립트가 활성화된 경우 WAN 인터페이스에 대한 WAN(Wide Area Network) 모니터링 소프트웨어 역할을 하며 WAN 링크 또는 터널 오류로부터 복구하기 위해 점점 더 간섭적인 작업을 수행합니다.
라우터에서 WANMON이 활성화되면 스크립트가 tmpsys:/eem_policy/ 디렉토리로 추출되며 이 명령을 사용하여 스크립트를 볼 수 있습니다. Router#more tmpsys:eem_policy/tm_wanmon.tcl.
사전 요구 사항
요구 사항
Cisco에서는 이 문서에 설명된 대로 TCL 스크립트를 활성화하는 것이 좋습니다. http://www.cisco.com/c/en/us/td/docs/routers/connectedgrid/cgr1000/ios/software/15_4_1_cg/WANMon.html입니다.
최소 소프트웨어:Cisco IOS 릴리스 15.4(1)CG.
사용되는 구성 요소
이 문서의 정보는 CGR1120/CGR1240을 기반으로 합니다.
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다.이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다.현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.
문제 해결 방법
WANMON이 구성되어 CGR에서 실행되는 경우 이 컨피그레이션을 디바이스의 컨피그레이션에 추가할 때 스크립트에 대한 디버깅을 활성화할 수 있습니다.

스크립트를 실행하는 동안 일반적인 문제
구문 오류
WANMON이 구성되었을 때 작동한다고 생각되는 상황이 발생할 수 있지만 실제로 영향을 주지 않습니다.예를 들어, WANMON 스크립트가 제대로 작동하지 않는 환경에서 이 디버그 출력이 관찰되었습니다.

이 출력에 따라 인터페이스 이름과 해당 번호 사이에 공백이 있기 때문에 스크립트가 성공적으로 실행되지 않습니다.이 오류를 일으킨 명령:
event manager environment wanmon_if_list1 {gig 2/1 {recovery {5 25} {90 180} {400 100}} }
올바른 구성은 다음과 같아야 합니다.
event manager environment wanmon_if_list1 {gig2/1 {recovery {5 25} {90 180} {400 100}} }
IPSLA(Internet Protocol Service Level Agreement) 다운
WANMON이 IPSLA로 여러 인터페이스를 폴링하는 경우
IPSLA 작업은 장애 위치를 즉시 확인하는 것이 어려울 수 있습니다.이 디버그 출력은 각 인터페이스에서 IP SLA를 사용하는 WANMON에서 두 인터페이스를 모니터링할 때 발생하는 상황을 보여줍니다.
